BB checks, Hero bets $5, Villain raises to $10, BB folds, Hero ...?

Villain had been calling lots of my raises and then folded on the flop to my continuation bet so I had started raising him with trash and he kept calling and folding. The table in general was very weak/tight and I had been playing pretty wildly this far expecting someone to make a stand sooner or later. So what's my play here?
